GEMBus Based Services Composition Platform for Cloud PaaS

Cloud Platform as a Service (PaaS) provides an environment for creating and deploying applications using one of popular development platforms. This paper presents a practical solution for building a service composition platform based on the GEMBus (GEANT Multi-domain Bus) that extends the industry accepted Enterprise Service Bus (ESB) platform with automated services composition functionality and core services to support federated network access to distributed applications and resources, primarily targeted for GEANT research and academic community. The ESB is widely used as a platform for SOA and Web Services based integrated enterprise solutions.
